We demonstrate that single pulse all optical helicity independent switching can be generalized for a large range of rare earth–transition metal multilayers. The threshold fluence for switching is observed to be independent of the pulse duration and, at high laser intensities, concentric ring domain structures are induced, unveiling multiple fluence thresholds. These striking switching features […]

We demonstrate that a perpendicular magnetic tunnel junction (MTJ) is capable of emulating an artificial spiked neuron. The magnetic stack has been designed so that the MTJ has two free layers, whose magnetization can be driven in a windmill-like dynamic by the spin transfer torque. The output-spiking rate is tunable by the dc bias voltage. […]

Spintec laboratory is opening a up-to three years engineer researcher position in the framework of the PEPR electronics (part of France 2030 strategy) – project EMCOM (emerging memories for computing).   Context: The cost of transferring information between different layers of storage and computing units now domi-nates the energy performance of conventional processors. This has […]

On Thursday October 26th 2023, we have the pleasure to welcome in SPINTEC Claire Donnelly from Max Planck Institute for Chemical Physics of Solids, Dresden, Germany and guest Professor at UGA for one month. She will give us a seminar at 10:00 entitled : Mapping and controlling three dimensional topological magnetic textures Place : IRIG/SPINTEC, […]

The large magnetometers currently used onboard satellites for space exploration cannot be installed in the tiny nanosatellites (cubesat) that are envisioned for multipoint measurements. As a first step towards the realization of a miniature space magnetometer, Spintec has demonstrated a strong amplification of the sensitivity of a magnetic field sensor on chip. The current magnetometers […]

Bayesian NN (BayNN) using Dropout-based approximation provides a systematic approach for estimating the uncertainty of predictions. Despite such merit, they are not suitable for implementation in an embedded device and in most cases cannot meet high-performance demands for certain applications. Computation in-memory (CiM) architecture with spintronics emerging non-volatile memories (NVMs) is a great candidate for […]

Context The automated resolution of cognitive tasks primarily relies on learning algorithms applied to neural networks which, when executed on standard CMOS based digital architectures, lead to a power consumption several orders of magnitude larger than what the brain would require. Moreover, Conventional Edge neural network solutions can only provide output predictions, lacking the ability […]

On October 18th 2023, we have the pleasure to welcome in SPINTEC Pascal Thibaudeau From CEA/DAM Le Ripault. He will give us a seminar at 11:00 entitled : Spinning in a bath: thermal handshakes of rotating particles Place : IRIG/SPINTEC, auditorium 445 CEA Building 10.05 (access to CEA (*)) skype link : https://webconf.cea.fr/ioan-lucian.prejbeanu/C89D5FFJ If the […]
